ABSTRACT:
An optical communication terminal detects an unused first wavelength in a wavelength range in response to a transmission request and transmits a call signal to a transmission destination using the first wavelength. An acknowledgement signal from the destination is detected in a portion of the wavelength range not including the first wavelength. When a call signal addressed to the terminal from another terminal is detected thereat and the terminal is ready for communication, an unused second wavelength in the wavelength range is detected and an acknowledgement signal is sent using the second wavelength in response to the call signal.
